Capra nubiana F. Cuvier, 1825.

The Nubian Ibex is a large relative of the domestic goat; its head-and-body length is 105-125 cm long and 65-75 cm high at the shoulder. The upper parts are brownish with a dark crest along the spine. The nose is black, and there are black markings on the legs. The male has a black beard, and powerful ridged and backswept horns. The female is beardless with smaller and smoother horns. The Nubian Ibex is remarkable for its agility; it lives in rocky wadis, cliffs, and mountains where it can climb very rapidly. It eats acacia leaves, woody shrubs, and roots and must drink every day; sometimes it travels long distances to find water. Mating is during late summer when the males become aggressive towards other males. After a gestation period of five months, one or two young are born. Its predators were formerly Leopards, but nowadays they are vulnerable to hunters when they come down from the mountains to drink and are now endangered.
